United States Patent HOG RINGER William Ray Van Zante, 'Otley, IowaApplication May 4, 1954, Serial No. 427,424

Claims. (Cl. 1-187) This invention relates to a hog ringer, and morespecifically is concerned with a hand tool for automatically applyingconventional clips of the type formed from bendable metallic wire andinitially having a substantially U-shape and being bendable to a closedlooped condition when applied.

An object of this invention is to provide a hog ringer having a pair ofmovable and pivotal jaws for engaging successive single wire clips fordeforming the U-shaped clips into a substantially looped clip therebyclinching the clip as desired.

Yet another object of this invention is to provide a hog ringer having amanually movable handle for providing the force necessary to clinch thehog ring and also provided with means for automatically feeding a singleclip into the hog ringer and automatically returning the hog ringer toan initial position for repeat performance of the clinching operation.

A still further object of this invention is to provide a hog ringerwhich is simple in construction, easy to use, efficient in operation,Well adapted for its intended purposes and relatively inexpensive tomanufacture.

These, together with other objects and advantages which will becomesubsequently apparent reside in the details of construction andoperation as more fully hereinafter described and claimed, referencebeing had to the accompanying drawings forming a part hereof, whereinlike numerals refer to like parts throughout, and in which:

Figure 1 is a side elevational view of the hog ringer of the presentinvention;

Figure 2 is a top plan view of the construction of Figure 1;

Figure 3 is a vertical section taken substantially along a plane throughthe longitudinal center line of the construction for showing theinternal arrangement of the pair of operating jaws and the actuationmeans therefor;

Figure 4 is a detailed perspective showing the jaw synchronizing meansand the means for separating adjacent clips;

Figure 5 is a sectional view similar to Figure 3 showing the details ofconstruction with the handle moved to the clinching position and therelative position of the jaws and hog ring clips; and

Figure 6 is a top plan view of a plurality of the hog rings which may besecured together for insertion in the hog ring supply magazine therebyeliminating the tedious process of loading the magazine.

Referring now specifically to the drawings, it will be seen that thenumeral 10 generally designates the hog ringer of the present inventionand includes a generally elongated flattened tubular hollow casing 12having a depending stationary handle 14 at one end thereof and having aU-shaped Opening 16 at the other end thereof for permitting discharge ofthe clinched hog rings or wire clips.

Referring now specifically to Figures 3 and 5, it will be seen that amovable handle 18 is pivotally mounted 2 ,756,427 Patented July 31, 1955ice on a suitable pivot pin 20 and the handle 18 projects through anopening 22 in the underside of the casing 12 and the inner end of thehandle 18 is provided with a curved portion generally indicated by thenumeral 24. The lower end of the handle 18 terminates substantially evenwith the handle member 14 and is shaped substantially in the nature of ahand grip 26. A screw threaded stop member 28 is threadedly engaged witha nut 30 secured to the forward edge of the tubular handle 14 forengaging the rear of the pivotal handle 18 when the handle 18 is movedtoward the stationary handle 14 for operation of the hog ringer 10, asdescribed hereinafter.

It will be seen that the outer or forward end of the casing 12 adjacentthe opening 16 is provided with a pair of inwardly converging upper andlower walls 32 and a pair of jaw members 34 engage the wall 32 forsliding movement thereon and the jaw members 34 are pivotally secured toa generally A-shaped connecting link 36. The jaws 34 are connected to acircular member 38 on each corner of the A-shaped link 36 by asubstantially curved portion 40 at the rear end of each of the jaws 34.The other end of the A-shaped link 36 is connected to the curved portion24 of the handle 18 by the use of a suitable circular member 42. It willbe seen that the movement of the handle 18 is transferred to theA-shaped link 36 and then to the jaw 34 wherein the jaws 34 moveforwardly and toward each other due to the convergence of the walls 32which slidably engage the jaws 34. The inner surface of each of the jaws34 is provided with a U-shaped recessed area 44 for receiving a T-shapedportion 46 of a synchronizing link 48 which has a rear end 50 engageablewith the A-shaped link 36. The synchronizing member 48 is provided witha right angularly extending lug 52 on one side thereof for projectingthrough an elongated slot 54 in one side of the casing 12 and a tensioncoil spring 56 is secured to the lug 52 at one end and to an upstandinglug 58 on the casing 12 at its other end for urging the jaws 34 and theA-shaped link 36 to a retracted position. An offset wedge member 60 isprovided on the synchronizing member 48 in opposing relation to the lug52 for separating a single U- shaped wire clip 62 from the next adjacentwire clip which it is secured to by suitable adhesive or other means fora purpose described hereinafter.

Referring now specifically to Figures 1 and 2, it will be seen that asupply magazine 64 is provided to one side of the casing 12 adjacent theforward end thereof and is in communication with the interior of thecasing 12 substantially just in front of the jaw members 34. Themagazine 64 is generally oval shaped and includes a pair of innermembers 66 which form a tubular member substantially the shape of theinner area of the U-shaped clip 62. An elongated longitudinal slot 68 isprovided in the upper and lower longitudinal edges of the magazine 64and right angularly extending slots 70 are in communication with theelongated slots 68 at their outer ends for a purpose describedhereinafter. An arm 72 of generally U-shaped construction is pivotallysecured to lugs 74 at the upper edge and lower edge of the casing 12 anda single arm 76 is pivotally secured to the bight portion of theU-shaped arm 72 by a suitable pivot pin 78. A torsion spring 80 ispositioned around the pivot pin 78 and has one end engaging the bightportion of the arm 72 and the other end hooked over the arm 76substantially as illustrated by the numeral 82. The outer end of thespring biased arm 76 is generally U-shape as indicated by the numeral 84and includes a handle member 86 for grasping with a fingerand'overcotningthe tension of the spring 80 wherein the inturned endportion 88 of the U-shaped arm may be moved in the slot 68 in themagazine 64. It will be seen that the inturned end portions 88 may bemoved into the laterally extending slots 7% thereby permitting theinsertion of a plurality of U-shaped wire clips as illustrated by thenumeral 90 that are formed in assembled relation and secured together bysuitable adhesive or other means thereby permitting the insertion of agroup of wire clips 90 with a single outward movement of the inturnedend portions 88, and the arm 76. Itwill 'be seen that the spring 80continuously urges the wire clip 90 toward the casing 12 for engagementby the jaws 34 and clinching as illustrated in Figure 5.

In operation, the handle 86 is pulled outwardly thereby moving theinturned end portions 88 of the arms 84 into the laterally extendingslot 70 thereby permitting the magazine 64 to be filled with a pluralityof secured together U-shaped wire clips, such as hog rings, andtheinturned end portions 88 are then moved back into the longitudinalslots 68 thereby urging thewire clips 90 toward the interior of thecasing 12. The innermost of the wire. clips fill as indicated by thenumeral 62 is positioned between the clip engaging seat 92 on each ofthe jaws 34 with the open portion of the clip 62 facing the opening 16in the outer end of the-casing 12. The movable handle 18 is then pivotedabout pivot pin 20 thereby urging the A- shaped link 36 forwardlytogether with the jaw members 34, which slide forwardly along the upperand lower walls 32 of the 'casing 12 wherein the walls 32 force the jawsinwardly into gripping engagement with the U-shaped clip, 62 therebyclinching the clip 62 substantially as illustrated in Figure 5. \Thejaws 34 slide along the walls 32 and also pivot about the circularmembers 38 on the end of the link 36. The transverse member 46 on thesynchronizing member 48 guide and limit the pivotal movement of the jaws34 since the transverse member 46 is loosely positioned in recesses 44which permits relative movement of the jaws caused by arcuate movementof point 42 thereby synchronizing their action and assuring accurateclinching of the clip 62. The action of the tension spring $6 returnsthe jaws 38 and the A-shaped link 36 as well as the handle 18 to theoriginal retracted position for a repeat operation. The sharpenedactuating said jaws, and interconnecting means provided member 69inserts itself between the innermost clip 62 V and the next adjacentclip thereto thereby separating the inner clip 62 for clinching.Obviously, the device may be constructed of any readily obtainablematerials and except for reloading the magazine occasionally, the deviceis completely automatic and of relatively simple construction.

From the foregoing, the construction and operation of the device will bereadily understood and further explanation is believed to beunnecessary. However, since numerous modifications and changes willreadily occur to those skilled in the art, it is not desired to limitthe invention to the exact construction shown and described, andaccordingly all suitable modifications and equivalents may be resortedto, falling within the scope of the appended claims. a
